My system help ?No room for back surrounds?

Is this your setup? If so there is so much wrong with this that there's no point to buy another speaker. You should get rid of all of these speakers except for the L/R and it would sound much better.

Clearly you're a 2 channel guy and a bit out of your depth here.

Ah, the missing tower. If you are ok with where the left speaker is, consider switching the right speaker and sub around so that the mains are both the same distance from the center/ tv. The mains don't have to face straight forward. Angle them in towards your seating position. My other advice still applies.

Look good. ? Surrounds are high enough cannot locate them while listening .

The RCA jacks on the sub are labeled "In" at the top and "Out" at the bottom. The connection at the sub should be the upper connector, not the lower. You have the correct side (the white side labeled "Left/Mono/LFE") but should be "In" to feed the sub. Mind you, the in and out jacks could be connected together in parallel, in which case it does not matter but better safe than sorry.
Moving the right speaker away from the wall can improve the sound a little. It is a matter of trial and error and what your ears think is best. Not a big deal.
To test the surrounds, do you have a blue-ray player? (I see some cases in the photo.) Make sure you have surround source like a blue-ray, not cable-TV, and check what surround mode your AVR is in. Most will show on the front display. You can try changing surround modes with the remote or front controls. If connected via HDMI cables, most AVRs will detect the surround mode automatically and display it. Analogue audio cables (red white) won't do that.
How many channels does your AVR have? If it is a 7.1, then you need to connect to the surrounds to the correct speaker terminals and setup the AVR properly. For example, with my AVR, I have the surrounds connected to the "Surround" terminals and the "Surr. Back / Amp Assign" is not connected. Then in the AVR setup I have speakers assigned to main, centre, surround and sub, with nothing on the surround back. You'll need to refer to the owners manual and setup instructions for speaker connections and setup. Then find an action movie and look for a scene with lots of sound effects to check for rear sound. Another test is the short Dolby THX welcome video at the start of some discs. That uses all speakers.

OK, in another thread you mention the Onkyo 818, so I assume the TX-NR818? For 5.1 setup it says to use the front L/R, center and surround L/R (the connectors on the far left and far right of the AVR). Wide, high and surround back not connected. This AVR has Audyssey automatic setup. Plug in the microphone and place it at your seating position and run Audussey speaker setup. It will send test tones to each speaker and automatically set the speaker configuration and levels. You should hear the surrounds during the test. If you can't find the manual, a PDF is here.

Onkyo 818 is 7ch I could run 9 with another amp but it’s not necessary. Yes there surround backs and side surrounds are slightly in front of me . How was I getting bass hooked to output lol ? No wonder was so boomy

Boomy could be another issue, like where the sub is located in the room, your seating position and how high the level on the sub is. Those are things you can play with to see what sounds best.
If those other small speakers are the side speakers, then they would go on the "wide" connectors and the surround speakers on the "surround" as mentioned above. I would still find the microphone and run the Audyssey speaker setup. The manual has a table on page 13 with check marks to show what speaker setups are supported and surround with front wide is ok.
