13 in particular is Nautilator's gun - the lobster guy
#3 hmmm. needs a bit more light and bigger pic. but it does appear to be both just Sixgun's gun as previously mentioned by 1Azrael1 already.
#6 and last one is of the same toyline which escapes my memory what the name is, but definitely not TF.
