They all look like 1950's. Nice you found Beer cans. The schlitz should have the dates right on them. Look closely at the writing near seam. one looks like a 1949 (browner version) & the other looks like a 1954 (redder maroon version). Now if those 5 cans were Apache cone tops from Phoenix I'd probably be giving you $1,000. Keep looking. LEON.
That rusty cone picture, looks like a good vintage flat bottom inverted ribbed cone from late 1935 to early 36. Could be some good cans buried there. LEON.
