a few colour patches for ID/help please

[badgecollector]

hi all
just need some help to ID some of these patches and some general information please.
unsure what the 4 yellow on black colour patches are in the left column.
the 3rd down may be 3rd MG but its feel is more of a ww2 period cloth and certainly denser than the 2 patches far right.

i cant find the bottom T patch in 2nd column in Glydes book? (got it, 9 Div HQ, Glyde 427)

what period do you think these are especially the 2 furthest on the right?

anyway, thanks in advance for your help

bc
