The Canada 155-159 on the black page appears to have the stamps mounted in old Crystal Mounts which are very bad indeed. They grip the stamps too tightly, and the glue used to seal them is dangerous to stamps. I'd very gently slit them open (they're stupidly sealed shut, another very bad idea) with a sharp pen knife or hobby knife, remove the stamps and store them in a stock book or on Vario pages for later re-mounting. Generally, Crystal Mounts are pretty much reviled nowadays. They're recognizable because they will have a distinctive brown glue strip visible through the mount (pretty ugly), glue may leak out, and the mount has rounded edges that wrap around the stamp (a bad idea) unlike modern mounts which simply "clasp" the stamp between front and back.
The stamps mounted on lined notebook paper may need to be removed, as well, and can be put into a stockbook or on Vario pages quickly and easily. The chance is relatively high that the notebook paper is cheap and acidic and might damage the stamps. Maybe not, but better safe than sorry.
Get rid of the photo album if it's the kind which has glue on the pages to hold photos. That glue is death to photos and will ruin stamps.
Be sure to use stamp tongs to handle stamps. After awhile, you'll find they're much better than even your hands and will damage stamps much less, keeping dirt and grease off them. Glassine envelopes are a good way to store bulk stamps for later sorting. Both tongs and glassine can be purchased on Amazon
and from many normal stamp suppliers like Subway, Amos Advantage, and others.
It's an excellent idea to remove the stamps and put them onto Vario (or other) stock pages, as you're doing. Store the binders upright in a place where the temp and the humidity don't wildly fluctuate where they will be safe (ie. NOT in a garage or basement ever). "Airing" them out which means just flipping through the pages once in awhile will also keep stamps fresh. Don't seal them up, in other words. You can store them in slipcases to keep dust and dirt away, and be aware that various household bugs eat paper, so keep them up off the floor and be watchful. Certain citrus smells and others tend to keep bugs away, I've read.
Keep at it! Nice collection, maybe better than my modest Canada collection.
