Standard shape glass bottles are, and those have the smallest deposit too: beer, soft drinks, water, I believe that's it? Non-standard glass bottles are recycled. PET and aluminum cans are obviously recycled, not reused, and have a steep 25¢ deposit.

For reference, Lidl (a German discount supermarket chain) advertises that ~50% of their bottles' PET comes from recycled bottles.

Glass water and beer bottles are reused, thick-walled PET water bottles are reused, while most plastic (mostly PET) bottles and all cans are, at best, recycled.

For other and broken glass items there are glass containers pretty much everywhere, broken up by color (white glass, brown glass, green glass). Plastics delivered by consumers are separated but never recycled.

Assuming we are still talking about Germany, yes, plastics collected via "Der Grüne Punkt" (engl. the green dot, named after the label on the packing) are in fact commonly reused.

According to official figures about 51% of plastics are recycled, 38% is burned [1].

In my state glass is neither reused nor recycled, it's crushed and used as filler for things like environmental drainage projects. A big part of the problem in rural areas is the cost to transport glass makes it worthless to buy and recycle, and there's a high contamination rate, so increasingly it's back to the landfill for glass.

Even better!
