1. Starting today on April 10, 2021 if I invested 150k in bitcoin, how much do the gurus expect me to have in 1, 2, 5, and 10 years? Like would any idiot who just invested today and didn't sell expect a 5x increase within the next 10 years?
Invest in Bitcoin for years while expecting 10x is not an idiot strategy because its something alot of people has been over the years but it good to understand the market halving season.
2. I would use dollar cost averaging, but over what time horizon? Invest 150k over the next six months? Or just invest it all today since we all know it's going up?

Time horizon doesn't come to play, the market trend is what you need to put into consideration cause the best time to invest is when people panic sell.
3. I could withdraw the old retirement fund and get the initial investment up to 300k. Would you go all in using that? I would not have much of a backup plan for retirement if this is the case, but like I said I have a high risk profile. I do believe this is once in a lifetime.

Going all in every investment setting is a wrong decision and I will advise you to invest 75K while you set aside 75k to buy more when there's some dump price in the market. Mind you, the first 75K was for long term investment while the 75K is for short/seizing the market opportunity and selling at profit price.
4. If I want to pursue some alt coins, and again, I have a high risk profile, what % mix would you recommend? 33% alt-coins and 66% bitcoin, or 50-50, etc?

Altcoin are high manipulated coins but since you have a high-risk profile, you can invest 20% in altcoin like BNB (keep on Binance to get some free coins which you can sell asap), ETH, Link, and DOT.
