The OP asks more than one different things: the classification of fin dim, semisimple (or not), braided Hopf algebras is still ana wide open area (up to my knowledge of course).

The classification of finite dimensional hopf superalgebras (the super- here is to be understood as the simplest case of braided) is another thing. It is still open in general, but a particular case of it has been solved long ago; this has to do with all the finite dimensional (super-)cocommutative hopf superalgebras. These have been classified by means of the following:

Let $\mathcal{H}$ be a finite dimensional, super-cocommutative, hopf superalgebra over an algebraically closed field $k$ of characteristic zero. Then $$\mathcal{H}\cong k[G(\mathcal{H})]\ltimes\bigwedge V$$ where $V$ is the space of primitive elements of $\mathcal{H}$ (regarded as an odd vector space), $\bigwedge V$ is its exterior algebra and $k[G(\mathcal{H})]$ is the group algebra of the the finite group $G(\mathcal{H})$ of the grouplikes of $\mathcal{H}$. In other words, $\mathcal{H}$ is a supergroup algebra.

Remarks:

  1. The above proposition generalizes the corresponding classification for the ungraded case (see for example: About the classification of commutative and of cocommutative, fin. dim. Hopf algebras)
  2. The above proposition, can be seen as a corollary (in the fin dim case) of the super-version of the Cartier-Constant-Milnor-Moore classification theorem, which is actually a classification result of super-cocommutative hopf superalgebras:

Let $\mathcal{H}$ be a super-cocommutative hopf superalgebra over an algebraically closed field $k$ of char zero. Then we have the hopf superalgebra isomorphism: $$ \mathcal{H}\cong k[G(\mathcal{H})]\ltimes_{\pi} U\big(P(\mathcal{H})\big) $$ where, $k[G(\mathcal{H})]$ is the group algebra of the the group $G(\mathcal{H})$ of the grouplikes of $\mathcal{H}$, $U\big(P(\mathcal{H})\big)$ is the universal enveloping algebra of the lie superalgebra $P(\mathcal{H})$ of the primitive elements of $\mathcal{H}$ and the smash product $\ltimes_{\pi}$ is with respect to the representation of $G(\mathcal{H})$ on $P(\mathcal{H})$ determined by: $\pi:G\to Aut(P)$, $\pi(g)x=gxg^{-1}$, for all $g\in G$, $x\in P$.

Furthermore, the hopf superalgebra $\mathcal{H}$ is finite dimensional if and only if $G(\mathcal{H})$ is a finite group and $P(\mathcal{H})$ is finite dimensional and purely odd (thus: an abelian lie superalgebra).
