These theoretical maximums you describe can only apply for an Earth originating organism.

When observing Space in search for “life” we should keep in mind that the term life is subjective. There could be “life” forms, made primarily from gaseous materials (hydrogen or helium) on a gas giant per say.

So gravity would matter less for them due to their superlight nature, and you can certainly forget about skeletal and blood circulating structures all together.

Or even life forms with Iridium as their base element instead of carbon which is the cornerstone of the life forms we call ‘organisms’ here on Earth. Incidentally, when one considers the fact that Iridium is by far a more common element found in space than carbon is, can easily predict that the chance of an iridium based 'life' form to exist somewhere far exceeds the chance of another (Earth organisms) carbon based one.

The term 'life' is a very relative one when space is brought into the equation.

True - though we have no evidence of such life existing. Regardless - my reply was strictly in reference to organisms - not life in general.

Not necessarily the higher the gravity I'm pretty sure it means animals would have to be lower to the floor so animals walking on two legs are unlikley but I do believe larger forms of insects like centipedes hs been said to be a possibility look at some of the life forms found in trenches deep beneath the ocean and deep underground where the effect of gravity is a fair bit stronger.
