There's only a few things I see that will bring you more of what you already have, and only a couple things that will make different morphs than what you already have.
Your male Bell... Well if bred to your Bell female, of course you'll just get more Bells. Breeding with any other female will just get you hets. Definitely don't breed with your Tremper. You'll just get possible hets of both...
Your male SHCT would go best with your Tang to start a SHTCH line going if you want to go that direction. Breeding with your Choc Tang Albino will give you a mix of dark and light Tangs, Hypo Tangs, CTs and the like, all het for Tremper.
Your male Sunglow would be best with your Tremper to produce more SunGlows or if your Tangerine is of better quality than your SunGlow you might wanna breed with her to see if you can get brighter SHTCTs het for Tremper that you can breed the following year to strengthen the color and start a good SunGlow line.
Your Jungle male will be best with your RS Jungle to produce more Jungles.
Your Mack Snow male is your best shot with anything. He'll produce Mack Snows with any of these females. If bred to your Tremper, you can get Tremper hets and the following year you can have a shot at Tremper Snows and/or Tremper Super Snows. I wouldn't breed with anything that's a line bred (i.e. your Tangs) as it's hard to breed out the orange once the offspring exhibit it. (I personally like whiter snows w/ no yellows) You can do the same as the previous with your Bell to get the same. Breeding with your Jungle will probably not get your Mack Jungles as there's a debate as to whether Jungles are a line bred or an Incomplete Recessive. If it's an IR, then you won't get any, which a lot of people say usually happens. (I personally never bred Jungles so I can't say) But if it happens to be a line bred you may get Mack Jungles. Hope someone else with Jungle experience can clarify that.
These are your options for this year's offspring. If you're looking further into the future, then I suggest taking your Mack and breeding with Your RS Jungle, Bell, and Tremper. You won't get anything much this year, but the following year, your hets will produce better stuff. (Tremper Macks, Bell Macks, Supers, Jungle Macks, etc...) You can't really do much with your SunGlow but enhance the colors so he's only good with your Tang or the Trempers. I'm not a SHTCT person so I'm a little biased on using your SHCT male.

Sorry lol. It's best he go with your Tang though to add some Tangerine colors to your offspring...
Hope this helps.
