An antiquark is an antiparticle of a quark.
An anti-up quark is an antiquark which corresponds to the up quark.
An anti-strange quark is an antiquark corresponding to the strange quark.
A meson is comprised of one quark and one antiquark. Another way to comment on the composition of the meson might be that it contains a quark-antiquark pair. A link can be found below for more information.
An antibottom quark is another name for the bottom antiquark, the antiparticle of the bottom quark.
A meson is made of quarks - specifically a quark-antiquark pair. Some are called pions and kaons. They are all short lived particles that have been identified from high energy collisions. See Wikipedia for more detail.

Pion is another name for "pi meson". They're mesons composed of an up or down quark and an up or down antiquark. "Mixed" mesons (one up, one down) are charged;the form where both the quark and antiquark are up or down are neutral.
