They mostly secrete proteins...
yep
Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.

they are found in animal cells
The secretory cell i.e the epithelial cells of stomach, or cells of glands etc are mostly rich in lysosomes. Because lysosome works as secretory vesicles.
Yes
This is the IB answer key to this Question: secretory cells arranged in layer one cell thick; cells contain secretory vesicles; cells are grouped in acini; surrounded by basement membrane; cells adjacent to duct/lumen;
Lipid Bilayer
no
it modifies substances produce by the ER(endoplasmic reticulum) and packages the subs into secretory vesicles.

vesicles are found in both animal and plant cells.
