Wouldn't you have less loss as you don't have to go through all that atmosphere?... Of course we did it on PCSAT and ISS... :)
Yes, but communictions loss is almost insignificant going through Atmosphere except at some very high microwave frequencies. The Biggest loss in any comm link is the DISTANCE term. It is 192dB
for going 40,000 km at 2.4 GHz. 192 dB is 10 to the 19th. That is, the signal is one divided by 16,000,000,000,000,000,000.
It takes power and/or a lot of antenna gain to make up for that. Bob

Could User#1 uplink to Sat-A and then Sat-A would link to
Sat-B
Its rather easy to evaluate that situation. Look at what it takes for a user uplink and downlink station just to hit the satellite. Now imagine that you are asking for all that
power
and gain antennas to be added to one satelite just so now
this
one satellite can work another satellite. As you can see,
it is
pretty much impractical.
