Here's a list of all the skills for Crystal Story 2 for each character (as of v1.20). A character can pick two specializations for each class tier, and a third after two Class V specialization trees are completed (after around 365k SP total), as well as a fourth specialization at 1.1 million SP, although by this point it's mainly for upping your stats.
D has Slayer I selected at the start of the game, Lina has Thief I, and Mari has Elementalist I.

Notes:
- Base SP Cost only displays the cost of learning the first two specializations, and rises as you go though the skill path. Skill cost is 1.2x base SP. There are 20-23 stat increasing nodes per specialization, and the amount of stats gained from a node varies slightly per character.
- Anything in cyan are skills unique to the character.
- Fire Attack, Frost Attack, Lightning Attack, and Earth Attack deal elemental damage based off the ATK stat instead of the MAG stat.
- Guard, Recovery, Concentrate, Berserk, and Reinforce targets self.
- Guard: Reduces the damage of next attack by half
- Recovery: Casts Regen (late game this is pretty much useless)
- Concentrate: Gives ATK Up and MAG Up
- Berserk: Gives ATK Up, MAG Up, and SPD Up
- Reinforce: Gives DEF Up and MDEF Up
- Throw Burst 1, 2, 3 are the only skills which allow you to use offensive weapons in your inventory.
- Hide prevents enemies from chasing you when used on the field map for a while (you can still start an encounter if you run into an enemy), and Sprint doubles your movement speed on the map.
- Lightning actually inflicts Wind damage. Don't ask why.
- Holy Light applies Greater Heal to all allies.
- Auto Raise gives the party Auto-Life status, fixed in v1.3.
A good strat would be to get a dedicated buff/debuffer with high speed with the Start SPD accessory (one is obtainable after completing Mercenary Defense Lvl 3) to allow multiple turns at the start of battle to buff the party's defenses and speed, and the other party members for offensive attacks and possibly debuff the enemy.
Focus less on stat gains and more on desired skills when deciding what class to give your character. When choosing between two stat gains always go for the HP/MP increase, since the other stats are easier to get via equipment + upgrades and the only increases to DEF or MDEF are accessories or buffs (in the latter case it's a 25% damage decrease). Bosses (and many enemies scaled up when Wanted X Quests / Hard Mode is activated) are capable of one shotting you / entire party otherwise, sometimes before you can even make a move.
I don't have exact specifications at the moment on how many of each upgrade are present when going through each class specialization. The table might be more useful on the wikia for this game, but the visual graphic that will soon replace the above tables will remain here.
