I don't study post marks beyond numerals, so I won't be much help on the ones with a cds, but I'll go through the ones I can.
The 2nd image, 6d Queen on Throne (printed in England by Perkins, Bacon & Co - with the 1d green of the same design the only stamps not printed in Vic.) The barred numeral is 15x - I can't make out the last number. Are you able to determine what it might be? Perhaps enhance the image using different filters, or view the stamp under magnification etc. It would be worth finding out, a few of the 150's are rare.
Next is 4d red Emblem, roulette, barred numeral 3 of Castlemaine (gold mining district.) My 1st Australian ancestors are from there

Not rated (meaning common.)
The 7th image, the 2d Laureate with the missing frame (which I'll cover separately) barred numeral 11 of Williamstown. Not rated.
Next is the 1d green Laureate with a type KA Melbourne number 1 killer. The thickness and height of the solid 1 varies. They're all common.
Further down the 3d orange, also part of what's known as the Laureate series, barred 71 of Richmond. This was the 2nd duplex issued in 1870. Not rated.
Below that you have the same design that was resurrected in 1901 and has the word postage added. Would need watermark & perf to be more specific. It has the 5 of Ballarat - 16th duplex. Not rated.
Next is an earlier version of the 5 of Ballarat, I'm thinking 4th duplex without measuring. Also not rated (Ballarat was a large town.)
Below that is the barred numeral 200 of South Yarra. Hard to determine the duplex with a light impression. I'm thinking 3rd duplex. Perf & watermark of the stamp might narrow it down.
Next is 125 of Kew (non duplex.) Not rated.
Followed by number 10 of Warrnambool. 3rd duplex I think (if the 1 is 8mm high) Not rated.
The 6d blue with stamp duty incribed, 113 of Mornington. Not rated.
Further down the next 6d blue has the number 4 of Bendigo (previously Sandhurst,) 1st Bendigo duplex, issued 1891.
Below that is the number 5 of Ballarat again, this one 11th or 12th duplex (would need some measurements) but neither are rated.
The 1s orange (or yellow as it's referred as) about 11 up appears CTO.
I have to leave it at that for now, run out of time. I'll get back to the laureate with the missing frame and if you have any other questions on specific stamps let me know.
